Nogging or "noggin" refers to horizontal bracing pieces, typically made of timber or metal, that are installed between vertical studs in a wall frame. The primary purpose of noggings is to provide lateral support to the studs, helping to prevent them from twisting or buckling and to increase the overall rigidity and stability of the wall structure. Noggings also offer additional support for attaching fixtures, such as cabinets or wall linings. The spacing and size of noggings can vary depending on the specific requirements of the construction project and the load-bearing needs of the wall.

Noggings are commonly used in wall framing, ceiling framing, and floor framing to ensure the structural integrity of the building. They help distribute the load evenly across the studs or joists, preventing sagging or bending. Additionally, noggings can be used to attach various building components, such as insulation, wiring, or drywall, providing a secure and stable surface for these materials.

Purpose of Noggings

Noggings serve several purposes in commercial construction projects:

•  They provide lateral relief to the wall linings, allowing the head track more freedom to move with the structure it is fixed to, and limit the movement of the wall linings .
•  They prevent twisting of the studs during the installation of the lining boards, ensuring the stability and strength of the building .
•  They can accommodate additional loads, such as those imposed by tap sets, baths, and sinks, and provide a fixing point for these items

In wall framing, noggings are installed between the vertical studs to provide support for the wall structure and to create spaces for electrical wiring, plumbing, or other services. They also help to maintain the straightness of the wall and prevent it from bowing or twisting.

In ceiling framing, noggings are placed between the joists to provide support for the ceiling structure and to create spaces for electrical wiring, lighting fixtures, or other ceiling-mounted components. They also help to distribute the load evenly across the joists, preventing sagging or deflection.

In floor framing, noggings are installed between the floor joists to provide additional support and to create spaces for electrical wiring, plumbing, or other services. They also help to distribute the load evenly across the joists, preventing sagging or deflection.

Noggings are typically made of timber or metal, depending on the specific requirements of the project. Timber noggings are commonly used in residential construction, while metal noggings are often used in commercial construction due to their greater strength and durability.
